To all whom .itma/y concern:

Be it known that I, WILLIAM C. Rroxn'rrs, a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Im rovements in Re ulatorsfor Automatica y Controlling the low and Temperature of Liquids and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others, as well as those skilledin the art to which it appertains, to make and use the same,referencebeing had to the accompanying drawings, and to the letters of referencemarked" thereon, which .form a part of this specification.

My invention relates to a re ulator for automatically controlling the owand temperature of liquids, or, in other words, means wherebyflowmgliquids may be so manippefl'ectthe tem erature and pressure ofthis same as,desi-red I While my device is intended and designed moredirectly and particularly for automatically and. adjustably manipulating'the wain which connection it is herein il ter for baths andvariouspurposes generally, ustrate'd, described, and claimed, it will beobvious that said device may be similarly used to equal advantage forother kinds of liquids and for any other purpose desired-as, for

duce 'a deviceof the character an example, for service in plants, &c. rSome of the principal objects of my invenpapermills, dairy tion consist,first, in producing a deviceto so efiect the temperature and'pressure ofthe feed-waters un er varying conditions,where by there will always beestablished an even and unvarying or desired degree of temper ature ofthe-mixture or water as discharged therefrom ,second, to-so constructsaid device as to provide means for automatically and adjustablyaccomplishing the objects abovestated, further objects bein kind. asherein referred to that consists offew parts, can be readilytaken'apart'for cleaning, &c., is simple in construction, inexpensive incost of manufacture, and eflective'in its results.

I My invention consists, essentially, referring ingeneral terms to theconstruction of my regulator .for automatically 1 controlling the flowand temperature of liquids, of the. body provided with the receivingends, the valve as will be hereinafter more fully described in toprosleeve or collar provided, with the slotted ports, the sliding valveprovided with slotted ports, the expanding stem and hand-wheel, theconnecting-pip the discharge end having the discharge or mouth, the dialand indicating hand or pointer, and the minor arts connecting therewith,and thepeculiar and novel construction, arrangement, and combination ofthese various mechanical parts,

: which will pass up connecting pipe L andinto astem Zc, said stemi beinintended in practice discharge end Mjand out through discharge or,

.ed upon; expanding stemJc and retained in position by means of a smallset-screw v at its head or socket is an indicating hand or pointer in,which, being thus firmly retained,

will move with said stem, when turned by operatin itshand-wheel, asabove described,

. until indicating-hand w will indicate or point pose of fully settingforth and clearly explaining my invention in detail, I have illustratedmy device as having the'indi'ca'tinghand pointing to the wordblormahf asin ,dicated by its arrow on the. dial, and all the 'partshave nowibeenmoved to their relative positions, as heretofore fullydescribed, so

that the feediwaters coming from any source of sup ply',throughreceiving ends I) andc as they rush together and intermingle willproduce-a mixture which will be discharged fromimouth m, 'havin a normaldegree of "temperature, as desire t It will of course be obvious thatthe operation of this device will always be the same in" any case, nomatter what the temperature of the water desired is. Now suppose it isdesired to have hot water discharged from the outlet to be connected tomouth m. By simply turnin hand-wheel Q until indicatinghand w wil restoverthe arrow leading or pointing from the word Hot, when expanding-stem70 will have turned, by reason of its screw-threads at p and i, justsufliciently to move or raise valve g, which is forced to move in thepro er direction by reason of set-screw e, which now acts as a stop,until slotted ports q of valve 9 will have'fully registered or coincidedwith slotted ports 1' of valve sleeve or collar d, when an opencommunication will have thus been established with the interior of valve9, and the hot water from receiving end I) will rush in, whilesimultaneously therewith cold-water ports 8 on opposite side of valve 9will have slid past and above ports t on this side and in valvesleeve(1, and ports t will have thus been closed by the walls of said valve,while the hot water, which has entered from opposite side, will pass upthrough the connecting pipe, discharge end, and discharge or mouththrough the outlet means, the same as in the case of the water having anormal temperature, as heretofore described. Slotted ports r and t inthe valve-sleeve (1, also slotted ports g and s in valve 9, are intendedto be simply narrow slots cut by a circular saw into said valve-sleeveand said valve, both of which are hollow cylindrical bodies, and theslotted ortsfar'e cut in a row or series on each si e thereof, and runonly sufficiently deep so as not to weaken these bodies. The slots orports in the row on each side of the valve-sleeve are to coincide witheach other or come on a horizontal line one with the other, while theslots or ports as cut on one side of the sliding valve are to dovetailor alternate with those in the opposite side of the valve, as shown.

Constructing "expanding stem 7c out of zinc or similar material, thusmaking it ve sensitive to any change in temperature,

cause it .to readily .contract or expand, ac

cording to the temperature of the water, thus causing it toautomatically assist in operating the device;-but the principaladvantage consists in the fact that should there be. any variation ofthe temperature of the hot or eoldfeed-waters as they come from thesource of supply when the device is set for water of a certaintemperature, this change will be automatically corrected through theexpansion or contraction of said stem, thus always automaticallyregulating the valve and the ports so as to offset this chan e, and

thus equalizing these difierences, w ereby an even, proper, and desireddegree oftemperature, as first started with, Wlll be the result, so thatthese changes will never aflect the'water as it comes from the dischargeor One very important feature of my invention and'which gives my devices ecial advantage is that the temperature of ischarged water can neverexceed a. temperature of 120,

.which is as high as the average person can stand or endure, and this isowing to the construction ofvthe stem, which 1s so verysensitive thatany greater degree of heat will have 7 5 caused said stem to expand tosuch an extent as to have entirely closed the ports, the space betweenwhich, as stated, is not very great. c

It will of course be obvious and readily understood that my device maybe constructed in various sizes, according to the special use for whichit may in each instance be intended; also, that a greater orv lessernumherof ports than here shown may be employed, when so desired, so asto increase. or decrease the volume as discharged; also, that variousminor changes in the arran ement, construction, and combination-of t edifferent parts as may from time to time be suggested may 0 be made, solong as confined to the spirit of this invention and not departing fromthe principles of the same.
